DEVICE FOR COMMUNICATING MOTION.

SPECIFICATION forming part of Letters Patent No. 243,175, dated June.21, 1881.

Application filed March 28, 1881.

To all whom it may concern:

Be it known that I, WILLIAM'M. TURNER, of Belle Union, in the county ofPutnam and State of Indiana, have invented certain new and usefulImprovements in Backlash-Springs; and I do hereby declare that thefollowing is a full, clear, and exact description of the invention,which will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,which form a part of this specifieation.

Figure l is a side view of-Iny invention. Fig. 2 is a verticaltransverse sectional view; and Fig. 3 is a horizontal cross-section onthe line a: x, Figs. 1 and 2.

Corresponding parts in the several figures are denoted by like lettersof reference.

This invention relates to an improved method of adjusting cogdrive-wheels upon shafts, so that the cogs or teeth shall not, as instarting or stopping, be exposed to any sudden jar or concussion, bywhich the said cogs or teeth are liable to be broken; and the inventionconsists in the improved construction and arran gement of parts, whichwill be hereinafter fully described, and particularly pointed out in theclaim.

In the drawings hereto annexed, A represents the shaft or spindle, uponwhich the main cog-wheel or drive-wheel B is loosely jouI-naled betweena collar, 0, and a clutch, D, both of which are firmly fixed upon theshaft. The under side of the gear-wheel B is provided with a stud, E,adapted to strike and engage the clutch, or when the motion of themachinery is reversed a stud, F, fixed upon the clutchcollar.

G is a coiled spring, having one end secured to the shaft A, aroundwhich it is wound, and having its other end attached to the gear-wheelB, as shown.

H is a wheel or disk, fixed upon shaft A below the gear-wheel B andspring G, and hav- (Model) ing secured to its upper face a series ofvertical spring-rods, I, passing through openings or perforations J in adisk, K, vertically adjustable upon shaft A by means of a set-screw, L,and extending through similar perforations M in the gear-wheel B.

From the foregoing description, taken in connection with the drawingshereto annexed, the operation and ad vantages of my invention will bereadily understood.

When power is applied to the shaft the resistance of the spring-rods Iand coiled spring G gradually imparts it to the gear-wheel until theclutch D strikes the studE, thus giving the motion direct to thegear-wheel.

By adjusting the disks H and K upon the shaft the tension of thespring-rods I may be adjusted as circumstances shall require.

It is obvious that this invention is equally well applicable tovertical, horizontal, and slanting shafts, the former being only shownfor purposes of illustration.

This invention is simple, durable, and useful, and when once applied isentirely automatic in its operation.

Having thus described my invention,-I claim and desire to secure byLetters Patentof the United States- The combination of the shaft A,gear-wheel B, having stud E and perforations M, collar 0, clutch D,having stud F, coiled spring G, disk H, having spring-rods I, and theadjustable disk K, havingperforations J, all arranged and operatingsubstantially as herein described, for the purpose shown and specified.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.
